Applying one layer of Bitumen Emulsion between surface below the road and the road surface which results in sticking two layers. It avoids slipping layers on each other. Cationic Rapid Set (CRS) or Cationic Slow Set (CSS) types of Bitumen Emulsion are used for this application.
1- This application is necessary to stick two asphalt layers together.
2- By applying Tack Coat, two layers act as one result in terms of consistency and stability.
3- It prevents the layers from slipping on each other. It acts as a bounder.
4- Only 400 to 800 grams of Bitumen Emulsion is needed to pave per each square meter.
5- It is cost efficient compared to other approaches.
